Abstract

A handling tool includes a body having a high-stress location, a pocket formed in the high stress location, and a sensor adhered to a surface of the pocket and oriented along an axis of the body. The sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location and is at least partially covered by a protective coating having a surface profile that matches a surface profile of the high-stress location. The sensor comprises a transmitter/receiver unit configured to communicate measurement data with a feedback unit via wired or wireless communication.

First claim

The invention claimed is:

1. A handling tool, comprising:
a body configured to support a tubular and having a high-stress location that is subject to at least one of radial loading and axial loading;
a pocket formed in the high stress location;
a sensor adhered to a surface of the pocket and oriented along an axis of the body, wherein the sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location;
a protective coating at least partially covering the sensor and having a surface profile that matches a surface profile of the high-stress location; and
a feedback unit, wherein the sensor comprises a transmitter/receiver unit configured to communicate measurement data with the feedback unit via wired or wireless communication.

2. The handling tool of claim 1 , wherein the body comprises a plurality of members that are hinged to a main body member to form a door.

3. The handling tool of claim 2 , wherein the door is movable between an open position and a closed position.

4. The handling tool of claim 2 , wherein the plurality of members include hinged plates, and wherein the high-stress location is in one of the hinged plates.

5. The handling tool of claim 2 , wherein the door includes a latch, and wherein the high-stress location is in the latch.

6. The handling tool of claim 2 , wherein the high stress location is in the main body member.

7. The handling tool of claim 1 , wherein the sensor includes one or more strain gauges.

8. The handling tool of claim 1 , wherein the sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location along three different axes of the body.

9. The handling tool of claim 1 , wherein the pocket includes a bottom surface and a sidewall, and wherein the sensor is adhered to the bottom surface.

10. A handling tool, comprising:
a body configured to support a tubular and having a high-stress location that is subject to at least one of radial loading and axial loading;
a pocket formed in the high stress location, wherein the pocket includes a bottom surface and a sidewall;
a sensor adhered to the bottom surface of the pocket and oriented along an axis of the body, wherein the sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location; and
a protective coating disposed in the pocket and covering the sensor such that the protective coating has a surface profile that matches a surface profile of the high-stress location.

11. The handling tool of claim 10 , further comprising a feedback unit, wherein the sensor comprises a transmitter/receiver unit configured to communicate measurement data with the feedback unit via wired or wireless communication.

12. The handling tool of claim 10 , wherein the sensor includes one or more strain gauges.

13. The handling tool of claim 10 , wherein the sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location along three different axes of the body.

14. A handling tool, comprising:
a body configured to support a tubular and having a high-stress location that is subject to at least one of radial loading and axial loading;
a pocket formed in the high stress location, wherein the pocket includes a bottom surface and a sidewall;
a sensor in direct contact with at least one of the bottom surface and the sidewall of the pocket and oriented along an axis of the body, wherein the sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location; and
a protective coating disposed in the pocket and covering the sensor such that the protective coating has a surface profile that matches a surface profile of the high-stress location.

15. The handling tool of claim 14 , further comprising a feedback unit, wherein the sensor comprises a transmitter/receiver unit configured to communicate measurement data with the feedback unit via wired or wireless communication.

16. The handling tool of claim 14 , wherein the sensor includes one or more strain gauges.

17. The handling tool of claim 14 , wherein the sensor is configured to measure at least one of stress, strain, load, and fatigue applied to the high-stress location along three different axes of the body.
